Connecting the Power Converter to the Power and Relay
Connector
Follow these steps to connect your switch to the power converter.
Warning
Use twisted-pair supply wires suitable for 86°F (30°C) above surrounding
ambient temperature outside the enclosure.
Statement 1067
Warning
This equipment is intended to be grounded to comply with emission and
immunity requirements. Ensure that the switch functional ground lug is
connected to earth ground during normal use.
Statement 1064
Caution
To make sure that the switch is reliably connected to earth ground, follow the
grounding procedure instructions in the
“Grounding the Switch” section on
page 3-15
, and use a UL-listed lug suitable for number-10 to 12 AWG wire and
an M-5 thread ground screw.
Note
For wire connections to the power and relay connector, you must use UL and CSA
rated, style 1007 or 1569 twisted-pair copper appliance wiring material (AWM)
wire (such as Belden part number 9318).
You must also use the ferrite that ships with the switch.
Step 1
Locate the Catalyst 2955 switch power and relay connector (see
Figure 3-5
).
Step 2
Identify the positive and return feed positions for the power and relay connector.
The positive DC power connection from power supply A is labeled VA, and the
return is the adjacent connection labeled RT. The positive DC power connection
from power supply B (the secondary power supply) is labeled VB, and the return
is the adjacent connection labeled RT.
